+ | * Switch 2 is RX audio sensitivity - on/up is low sensitivity for loud radios, off/down is high sensitivity for quiet radios | ||
+ | * Switch 3 is AC/DC coupling - normally should be off/down apart from specific radios | ||
+ | * Switch 4 is external carrier detect - normally should be off/down unless you need it for a specific purpose | ||
